The Duke and Duchess of Sussex are among the most followed couples in the world, so it comes as no surprise that when it comes to their security, they have secret code names.
To their bodyguards, the royal couple is not known as "Harry and Meghan" but there is some obvious logic to the names they've been assigned.
According to The Sun, the pair are referred to by their royal initials: "DS" - standing for the Duke and Duchess of Sussex.
And those initials stand for... wait for it... "David Stevens" and "Davina Scott".
With the world's media waiting to capture the couple's every move, a royal source revealed to the Daily Star that it is "far too risky" to call the Duke and Duchess by their actual names.
"If anyone got hold of a phone belonging to a royal aide or security team member, they won't find Harry Windsor and Meghan's names in it," they said.
They aren't the only royals to have their own code names either.
Prince William and Duchess Catherine go by the pseudonyms Danny Collins and Daphne Clark.
While it might be hard to think of William as a Danny or Catherine as a Daphne, their initials again give it away - "DC" - standing for the Duke and Duchess of Cambridge.
Apparently the code names are changed, though, to ensure maximum security, so it's unlikely we're going to overhear snippets of conversation among the bodyguards about a David or a Davina when the Duke and Duchess of Sussex arrive on our shores next month.
But we'll be keeping an ear out just in case!
